The roads not taken
endangered, the highest level of threat. But one of the real problems facing the IUCN is a lack of data. More than half the 44 cetacean species are considered “data deficient”, meaning future research on population numbers is a priority. And the worry is that more data could show more species in trouble. The blue whale, fin whale and sei whale all remain listed as endangered until more evidence...
متن کاملCorpora at Linguateca: Vision and roads taken
In the late nineties, access to Portuguese data in electronic form was scarce, and was considered one of the bottlenecks limiting the advance of natural language processing of Portuguese (Santos, 1999a), so Linguateca’s launching of AC/DC i had as purpose to significantly increase the amount of data – and its quality, in that the data was annotated and classified. To the best of my knowledge, A...
متن کاملFatty acid transport: the roads taken.
Efficient uptake and channeling of long-chain fatty acids (LCFAs) are critical cellular functions. Although spontaneous flip-flop of nonionized LCFAs from one leaflet of a bilayer to the other is rapid, evidence is emerging that proteins are important mediators and/or regulators of trafficking of LCFAs into and within cells. Genetic screens have led to the identification of proteins that are re...
متن کاملHuman Migrations: The Two Roads Taken
America was peopled from Asia by at least the end of the last ice age, but the exact timing of entry and the composition of the source population are unclear. A new analysis of two rare mitochondrial haplogroups suggests two separate Asian migrations into the Americas, indicating simultaneous but independent Asian source populations for early American colonists.
متن کاملThe Road not Taken: Less Traveled Roads from the TGN to the Plasma Membrane
The trans-Golgi network functions in the distribution of cargo into different transport vesicles that are destined to endosomes, lysosomes and the plasma membrane. Over the years, it has become clear that more than one transport pathway promotes plasma membrane localization of proteins. In spite of the importance of temporal and spatial control of protein localization at the plasma membrane, th...
